🎉 Congratulations on Receiving Your German VAT /OSS Number!

Your German registration, be it for OSS, VAT number (USt-IdNr.) and/or Steuernummer have now been officially issued — great news!
This means your registration in Germany is complete and you are now ready to begin compliant trading, invoicing, and reporting.

This article explains what you need to do next, how to manage communication with the German tax office, and how to keep your hellotax account fully updated.

✅ What You Should Do Now

1. Forward All Tax Office Letters or Emails to Your Account Manager

Once your VAT or OSS registration is active, the German tax office may send:

• Confirmation letters

• Requests for information

• Filing reminders

• General correspondence

If you receive any letter or email directly, please forward it immediately to your hellotax Account Manager.

Why this matters:

• The letter will be uploaded into your hellotax software account

• We maintain a complete and accurate history of your communication

• This ensures smooth handling during audits, queries, or verifications in the future

• Nothing gets lost or overlooked

Keeping a full correspondence trail is essential for long-term compliance.

2. Upload All Transaction Data on Time (Mandatory)

To ensure we can create accurate VAT and EC reports, all your transaction data ( including purchases and movement of goods) must be uploaded into your hellotax account by:

📅 The 4th day of the month following the period end

This applies to data from:

• Marketplaces (Amazon, eBay, etc.)

• Your own webshop

• Manual orders

• Returns, refunds, and cancellations

👉Data Upload / Integration

Please make sure your integrations and data uploads are consistent — missing data may cause incorrect filings, penalties, or tax office queries.

3. We Will Add Your New VAT Number & Valid-From Date

hellotax will enter into your software account:

• Your new German VAT number (USt-IdNr.)

• Your Steuernummer

• Your valid-from date (start date of your VAT obligations in Germany)

This ensures correct filing periods and prevents issues with your first returns.

4. Inform hellotax of Any Other VAT or OSS Registrations

If your business holds any other VAT numbers or an OSS registration in the EU (even if hellotax does NOT handle these countries), you must notify us.

Why this is important:

• VAT numbers in other countries affect intra-EU reporting, especially EC Sales Lists

• OSS registrations determine where and how VAT is filed

• Cross-border sales can impact your German VAT obligations

• It ensures we do not create conflicting or duplicated tax reports

• The tax office DOES compare VAT flows across the EU

A complete picture of your VAT landscape helps us ensure accurate, compliant reporting every time.
